Hello. The motion is taken from physics and the question is if the object falling freely for somehow equipped with an car meter to measure the distance it travels then the amount of distance it travels each succeeding second would be if aim falling freely then the okay object greater than seeking before. Double. So we know that uh G remain changeless when object freeform. Okay. And she is equal to DV over DT G is constant but speed is increasing with time. therefore if speed is increasing and then G is equal to D two X over D D square. So this implies G access directly proportional to the feather. So the value for this distance traveled will be increasing some square power so greater than the second ahead. So option C is the correct solution. There are not any other answer which is correct for the clock being. Okay, so this is first share and moment parties a feather and a coin will have the equal acceleration that is given to us when falling in a vacuum. Because acceleration due to gravity is lapp for each object in a vacuum. Okay, thus then sell for this question is choice B. That is acceleration due to graveness. Same for each object. That is an experiment done by the then by the Galileo. He saw a boastfully number of objects objects from the Pisa column, he observed that that each object will fall will possess adequate amount of acceleration or a ceaseless acceleration. Okay, so that is why the value of graveness. Same for each objective void. Okay, what ‘s option B is the right answer. and 3rd by this a falling skydiver of mars, 100 kilogram experienced 500 newton of atmosphere resistance. The acceleration of skydiver will be therefore acceleration is adequate to mg minus a rare exemplify. Um music uil 200 in two G. Stand minus air resistance is given to us 3500 which is equal to 500. We need to find the acceleration. Okay, acceleration is divided by M So 500 divided by full mass is already given to us. That is 100. So that will give you the rate of acceleration is 5m/s square. Okay so that will be five in two G. Stands for 0.5 in two G. Okay which is the ask solution for the given question and fourth separate here is a bowl choice D is the decline answer for this. A ball project state of what ‘s takes 10 seconds to go up and then return to the ground because of the air electric resistance. Time taken for down male child just go up is so they are saying that the publicize resistance act on it. So the value of jemaah islamiyah mechanically decreases so meter it will go off where it is Okay, Time it will take to go up is less than the 10 seconds Less than five seconds. Air electric resistance selecting the down direction. Poor management. Okay so the rate there is another quantity which opposed the value of and she Okay that is in the four directions thus that and we know that T. Is equal to two square two H by G. immediately G minus a resistance. Okay, so this will increase the rate of time, so the clock it will take is more than the five seconds, so Option B is the correct answer. so hope this.
